You poor dumb bastard, this is exactly why you climate cultists will never be taken seriously. If "they don't", whatever we do will be irrelevant. Further, the United States has been "leading" for 6 fucking decades while the big three polluters, China, Russia and India have done little to nothing. Beyond that there is zero conclusive evidence than man made emissions have any substantive impact on the overall climate that changes, has changed, and will continue to change regardless of what we do, or if human being even exist. Again, first you must explain in detail the why and how all climate shifts happened before industrialization or long before humans ever walked the earth, many of those shifts much more dramatic than we are now experiencing. And when you're done with all that then you can explain how taxing the U.S. into a third world shithole will help anything, anything at all.
